and adjustable holding means for holding the door in an open position.

It is, therefore, an object of the present in vention to provide a doorholding device which is particularly suited for use with slideconnections for doors.

It is another object to provide a door holder which may be readilyadjusted to alter the position in which the door may be held open.

It is a further object to provide a door .holder which may be easilyrendered operative or inoperative, and which is provided with a stop forlimiting the opening movement of a door when the holder is ininoperative position.

It is another object to provide a door holder which operates with aminimum amount of vibration and noise.

It is a further object to provide a door holder which may be easilyassembled on a slide bar without the aid of tools.

It is another object to provide a door holder which cooperates with astop, both of which may be regulated by a single adjustment.

These and other objects not specifically enumerated are contemplated forthis invention, as will be apparent to one skilled in the art as thefollowing description proceeds.

In the drawings- Figure 1 is a perspective view of a holding deviceconstructed and installed onv a door in accordance with the presentinvention.

Figure 2 is a side elevational view of a slide connection with theholding means in holding position.

Figure 3 is a fragmentary View in cross section of a slide connectionand holding means.

Figure 4 is a fragmentary view in cross section showing the holdingmeans in inoperative position.

Figure 5 is a cross sectional view taken on the line 55 of Figure 3.

Figure 6 is an end elevation of a device embodying this invention.

Referring to the drawings, a bracket or frame 9 is positioned within acut-out portion I I! in the upper edge of a door II. The frame may beformed from a single strip of metal having an upright portion 12 and abase portion 13. End

members I4 and I5 may be formed by bending upwardly the ends of the base[3. The base has openings to receive screws l6 which secure the frame tothe cut-out portion of the door.

A slide bar I! has journals I8 and I9 which are supported by suitablejournal bearings provided by the ends [4 and I5. The slide bar may be ofany cross section and is substantially square in the present embodiment.Thejbar-may be maintained in supported engagement with the frame in anysuitable manner, such as by a slip 20 engaging the end |5of the frameand a shoulderon the bar. An inwardly extending finger Y 2| may beprovided by the upright portion l2 for engaging the vbar and limitingits, rotation with respect to the frame. 7 V v The bar I! has a threadedportion 24 adjacent one end on which is screwed a stopor spring seat 22which is provided with an internalannular groove 23. A coil spring 25'isslidably mounted on the bar adjacent the spring seat 22.

A crosshead or slide 26 is slidably mounted on the bar I! and isprovided with bearing surfaces which conform to the cross sectionalshape of the bar. The slideis provided with a spindle 21 on which anoperating arm 28 is pivotally mounted, and a pin 29holds the arm onthespindle.

The undersurface of the slide bar is provided with a channel or groove33 which is of sufficient width to accommodate a curved resilientholding member 3|. The holding member 3| has a downwardly turned portion32, the end of which engages the annular groove 23 of the seat 22. Thecoil spring 25, through which the member 3| extends, may support themember in such a manner that the free end 33 of the member is maintainedinengagement with a cam rod 3'3.v

- The cam rod 34 extends substantially the length of the groove 30. Oneend of the rod extends through a hollow portion of bar I! and throughend member I4, terminating in a turned-down portion or crank 35. The rodis provided with a notch in its narrow surface for engaging a bearingpin 38 which extends across the groove 30' adjacent the end. The rod 34hasa width greater than its thickness. so that when it is turned up onedge by movement of the crank 35, the notched edge of the rod engagesthe pin and the narrow edge of the rod cams the end 33 of holder 3|downwardly. When the crank is turned the other way, as illustrated inFigure 6; the broader side of the rod engages the pin and the end 33 ofthe holder is permitted to move upwardly under the influence of coiledspring 25 which has previously sible from the top'of the door.

been distorted by the downward thrust of holder 3|. It will be notedthat it is not essential that the coil spring return the holder in themanner described since the slide Will move it up as it passes over theholder.

In operation, as the door II is opened, the bar I! moves with it and thearm 28, which is secured at one end to the door frame, causes the slide26 tomove toward the holding member 3|. When cam rod 34 is in theposition shown in Figure 2, with its wider surface in a verticalposition, it holds the central portion of the resilient holder 31 belowthe margins of groove 30. As the slide reaches the holder it passes overthe end 33 until the lower surface of the slidewedges against theundersurface of holder 3|. .The holder being resilient, the slide isfrictionally engaged and held with a minimum of noise and vibration. Aslight pressure on the door will release the slide and permit the doorto be returned to a closed position.

Torender the holderinoperative, thecrank .35 is moved so thatthe widesurface of the cam .rod 34. is in ahorizontal position, therebypermitting theholder tobe moved upwardly in the groove 30 astheslidepasses over it. The slide 26.may now pass over the holdern3luntil it en- .gages and compresses .coil spring-25 against thespringseat 22.

The position of the holder as -well as the coil spring :and spring seatmaybe-altered as a unit by merely screwingthespring seat 22 in thedesired direction. This maybe easily accomplished after the-device hasbeen installed in a door by rotating the spring seat, which is readilyacces- The downwardly turned end 32 of the holder freely rides in theannular groove 23 of the spring seat as it is revolved.

It will be noted that when the holder is in inoperative position it is.notnecessary that-all of member- 3| be maintained within the groove30,since slide Edwin-force theprotruding portion up in the grooveas itpasses over that portion of the slide-bar, provided the holder does notextend downiar enough to bind the slide -andfrictionally hold it, aswhen it is in operative position.

The curved shape of holder 3| and itsresiliency permit the slide tobecome gradually engaged and disengaged as it'approaches and recedesfrom a holdingposition, WlththB resultant smooth and quiet operation ofthe device.

It will be further noted that simplicity of construction of this deviceenables it to be completely assembled and installed without tools,

after the frame has been secured to the door.
